Hi,
The error code can be related to your HDD or just the OS going bad. Please do try these troubleshooting steps that may help in solving the issue.
- Firs is to do a hard reboot, remove the battery and unplug its AC adapter then press and hold the power button for 20 seconds then try booting it up again.
- If it does give you the same error your next course of action is to reload the operating system.
- Here's how to do a complete factory reset with your laptop.

- If factory reset will not work then it's the HDD that is faulty and replacing it would be the only way to go.
